IMPRovsD Sasa-BALANCE.' i

The Schedulereferred to in these Letters Patent and making part of the same.

Be it known that we, CHARLES KANZLR and AL- BER'riNEGA, of St. Louis,in.the county of St`. Louis, State of` Missouri, have made certain new and useful `Improvements in Window-Frames and Sashesfand we` do herebydeclare that the following is a full and' trueaccount thereof, `reference being had to the aecompanying drawings, and to 'the letters of reference This invention relates to the method of connecting window-xsashes with frames, and supporting the same Y To enable those herein skilled to make and use our #said invention, wel will now'lnore fnllydeseribe the same, refering herein to the-faccompanyin g Q Figure las a sectional elevation; to Figure 2 as a front view of the frame; to

i u ,i Ilignre3 as a detail side view of the sash; and to Figure 4 as a detail view of the rope-attachment. We form the frame A `in the general manner now usual, with the weight-boxes B ats'ides thereof.

. The sashes C slide between the strips, aa', in the Qnianner usual, and the same are 'suspended by ropes, e, `passing 'over pulleys D, and balanced by weights E.

lnorder that the sashes C may be put Yin place,

i withoutdisturbing the main strips a', and especiallyT the side strips aand be removed similarly, we arrange, .near i the bottom of the side frame, the removable Said piece is bevelled at upper and lower ends to fit the surrounding frame, and is heldin position, partly by its ,confinement between the end strips c, partly by its projection above and to the side of the sashpstile, Aand lastly, `by a slide,l`, the sliding bolt f whereof passesinto a proper mortise in the frame A. f Said, piece, A1, is formedof two parts, :A2 and A3,

connected by 'the side-strapsathe upper part, A, be i ing hinged at'the joint-bolt Vorscrew securing the straps" a2. j u

"llieoperator, by pressing up the bolt f, is enabled to draw outthe part A3,(the sashes G being raised and then the entirepieoeA1 is drawn out of its position. ',lhe sasliesC are then lowered, and by moving the same laterallybackinto the y mortise, formed by the l removal ofthe piece A1', tl 1e opposite stile may'theu be lswung out clear of the side strip of the frame, and

.thus the sashes may be lifted outof-the frame.

In order that the sashes thusreni'oved may bereleased from the ropes o,` we have arranged to lock the said ropes, so that, upon disconnection of the ropes, the

' rojections d, so that the operator in pressin the p a g knob d back, brings the mortises at its sides in vertital plane, so that said knob may pass through between the projections d2, thus bringing the slide D1 down upon `the ropes c, and retaining the same against the action of the weights, the springs d1 acting, in the mean time, to. press the slide D1 and knob d forward, s o that the projections d2 prevent the slideD1 from rising.4

The ropes c being thus secured, they may be disconnected from the sash-Stiles, and to facilitate. this operation, we arrange-a tie-plate, G, iu the rear face of the sash-stile, secured by proper screws'thereto.

Saidplate has a circular mortise, g, which connects with a slot, g. Said slot grows narrower toward its upper end, and the rope e being knotted at its end c', being passed into the lmortise g, will draw up in the slot gf, the knot falling back of the face-plate G, and b'eing prevented from disengagement by the projecting sides thereof. By simply drawing the rope downwardly, the disengagement is achieved.

.The sasli,.being thus removed, may be cleansed or repaired, and then again easily inserted.

Wedo not claim Aall the devices thus described;

neitheris it necessary that thev general arrangement of the rope-attachment or sash-construction berthe one heretofore described; bntthe parts here desiredl to be claimed asour invention, are as follows:-

. The rope-lock Dl clA dl d2, arranged and combined with the pulley D and'rope c, 'substantially as and for the purpose set forth. v
